Test conditions were maintained the same, as much as possible, over the platforms tested. For better comparison standard test results (1280x1024) were run with a single NVIDIA 7900GTX on all platforms. A single ATI X1900XT was also tested at standard resolutions on the ATI Reference board. Consider this result a sanity check for single card performance and Crossfire. It should not be directly compared to other test results. Since SLI and Crossfire are not yet interchangeable, 1600x1200 4xAA/8xAF SLI was run on the NVIDIA-based boards with a pair of 7900GTX. 1600X1200 4xAA/8xAF Crossfire was run on the ATI using an X1900 XT Master + Single Crossfire. All results are reported in our charts and color-coded for easier identification of results.

AM2 benchmarking used Corsair PC-8500 (DDR2-1066) 2GB kit at 3-3-3 timings at around 2.2V. In recent months the memory market has moved from a 1GB kit to a 2BG kit being the common memory configuration. Our new DDR2 test standard will therefore be 2GB and we used the 2GB DDR memory for best comparison.

    Asus opted to design for PCI access. With SLI using dual-width video cards there are still two PCI slots available, but the single x4 PCIe is covered. With single-width cards in SLI 3 PCI and an x4 PCIe are available.

    The picture of the motherboard on Newegg is different: the AT review shows a PCI slot above the black PCIe x16 slot...but the retail board at Newegg has a PCIe x1 slot. Except for that, everything else looks identical. Are there two versions of this board floating around? One with 3 PCI/1 PCIe x4 and the other with 2 PCI, 1 PCIe x4 and 1 PCIe x1?

    There are 2 versions of the board - with WiFi and without. The retail version we tested was WITH WiFi built in.
